[PATCH 3/7] afs: Need to clear responded flag in addr cursor

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In afs_select_fileserver(), we need to clear the ->responded flag in the
address list when reusing it.  We should also clear it in
afs_select_current_fileserver().

To this end, just memset() the object before initialising it.
